Industry-Leading 50-Year Transferable Warranty

Accoya is backed by an unmatched 50-year above-ground warranty and a 25-year warranty in ground and fresh water applications. Unlike many building materials, this warranty is transferable to future property owners, helping protect the long-term value of your investment.

Real Timber. Engineered to Perform. Built to Last.

Accoya Cladding is a high-performance architectural timber designed to deliver long-term durability without compromising on natural beauty.

Unlike traditional timber, Accoya is modified through a precision acetylation process that alters the wood at a cellular level. The result is timber that resists moisture absorption, dramatically reducing swelling, shrinking and decay.

The outcome is clean lines, long-term stability and a façade that performs for decades, even in demanding Australian environments including coastal regions, high humidity areas and extreme weather exposure.

Important Information

Natural Weathering or Coated Finish

Accoya Cladding can be:

Left unfinished to develop a natural silver-grey patina, or
Coated to achieve a controlled architectural finish

Thanks to its stability, coatings adhere better and last longer than on conventional timber.

Key Features

Exceptional Dimensional Stability

Accoya is engineered to resist movement caused by moisture. This means:

minimal warping or cupping
tighter joins and cleaner detailing
long-term façade integrity

Resistant to Rot, Fungi & Termites

Accoya’s modified wood structure provides exceptional resistance to biological degradation without relying on toxic preservatives, helping deliver long-term durability in demanding environments.

Sustainable & Non-Toxic

Made from FSC® certified timber, Accoya is non-toxic, fully recyclable, and free from harmful chemicals or biocides, making it one of the most environmentally responsible timber choices available.

Class 1 Durability

Tested to the highest durability classification, Accoya is designed for long-term exterior use, even in demanding Australian conditions.

Lightweight & Easy to Install

Low Maintenance Performance

With outstanding dimensional stability, Accoya requires significantly less maintenance than conventional timber. Coatings last longer, repainting intervals are extended, and the timber can even be left uncoated without compromising durability.

Real Timber Is Not a Substitute

Accoya retains the warmth, grain and character of natural wood, without the instability of traditional species or the compromises of composites.

Designed for Architectural Applications

Accoya is trusted globally for high-performance timber applications, including:

Saunas
Residential facades
Commercial buildings
Coastal and high-exposure environments
